I've had a problem for a few weeks now. The game starts to lock up after turn 200 or so. I end turn and it just stops for upwards of three minutes each time. If I wait it comes back but hangs on the next turn again and so forth.

This has only been a problem with the last patch and continued with the DLC, which I installed tonight.

I've tried the fast animation fix but it didn't help.

I'm running a Geforce 560 Ti, 16 gigs of ram, on an Intel Quadcore 3.30Ghz on Windows 10.
